Hi everyone Today i am going to tell you about total defence day.I will defence the air because if we did not have clean air,we will smell the smoke that will harm our body.Some air pollutants are poisonous. Inhaling them can increase the chance you'll have health problems. People with heart or lung disease, older adults and children are at greater risk from air pollution. Air pollution isn't just outside – the air inside buildings can also be polluted and affect your health.We can defend them by not smoking,start a fire and play fire craker.Air pollution is a mixture of solid particles and gases in the air. Car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles. Ozone, a gas, is a major part of air pollution in cities. When ozone forms air pollution, it's also called smog.So you know how serious Air Pollution can be so please do not pollution the air thank you.
